HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 900, 630, 19 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 900, 630, 19 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 900, 630, 19 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 900, 630, 19 is 1.
HCF(900, 630, 19) = 1
HCF of 900, 630, 19 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 900, 630, 19 is 1.
Highest Common Factor of 900,630,19 is 1
Step 1: Since 900 > 630, we apply the division lemma to 900 and 630, to get
900 = 630 x 1 + 270
Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 270 and 630, to get
630 = 270 x 2 + 90
Step 3: We consider the new divisor 270 and the new remainder 90, and apply the division lemma to get
270 = 90 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 90, the HCF of 900 and 630 is 90
Notice that 90 = HCF(270,90) = HCF(630,270) = HCF(900,630) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 90 > 19, we apply the division lemma to 90 and 19, to get
90 = 19 x 4 + 14
Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 14 and 19, to get
19 = 14 x 1 + 5
Step 3: We consider the new divisor 14 and the new remainder 5, and apply the division lemma to get
14 = 5 x 2 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 90 and 19 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(19,14) = HCF(90,19) .
